just gone through some insurance stuff for the touring and apparently it produces 4.8tonnes of co2 a year!! shocking!

over its lifetime an old car will produce less carbon that an old one as it is common knowledge the most emmisions a car produces is during the manufacture process, so by economies of scale an old car produces less CO2 per km then a new car despite the fact that new cars are more chemically effcicient, but they generally are not around long enough to make up for the more effcient engine as modern cars are effectively written off after 5 years.
So really by driving that old touring till its death you are doing your part for the environment as BMW do not need to kill the Earth making you a new one.
Final note:
For info to create 4.9 tons of CO2 you must burn 1870 litres of fuel, thats 35 litres a week , based on an average of 8l/100km (realistic for combined 325 driving) thats 23,375 km per year (or about 15,000 miles - not to unrealistic!!)
so yes your touring could produce 4.9 tons, b ut your neighbors brand new 320D is producing a whole load more!! Welcome to being green

note on further reasearch the amount of CO2 to make a car is supposed to be around 650kg, which is a figure provided by the car manufaturers
funny when you consider to make a ton of aluminium makes 12.1 tons CO2 and does not include shipping and further processing, a ton of steel is .4ton CO2 then all the plastics, fabrics, design costs, R&D and all those factoryt workers driving to the factory etc etc i very much doubt they can make a car for 650kg
Rant over

I'm afraid all this B***ocks, I hear every day about climate change & the environment really gets on my nerves. The environment is always changing, natural disasters, funny weather, global warming has been going on for millions of years. It doesn't make a single jot of difference how much C02 comes out of an E30s exhaust, its just another reason for government to heap more taxes & scare people.

im with you buddy,,, perhaps its all going pete tong for humans anyhows natural selection and all that
ahh well better enjoy as many cars as poss before its all over then

What winds me up is the way that the Nazis that pretend to run this country try to get us to pay more for having a bigger engined car. How does my 2.8L car wear the road more than a 1L car? It doesn't, but I have to pay twice as much road tax as a smaller engined car anyway.
They try to tell us that fuel is so expensive because it "offsets the carbon emissions". What are they doing with this money to "offset" the carbon, creating bloody oxygen isotopes to replenish the ozone layer? No, they're not.
How does paying the Government alot of money "offset" the amount of CO2 that comes out of my exhaust pipe?

There are people that believe the shite our Government come out with, aswell...
If I had to pay extra for fuel for having a big engined car, I'd still drive a guzzler, I'd just have less money.

Please don't confuse Green Taxes with being Green.
Taxes are taxes and they all go into the big pot that pays for carpeting the bastards moats and employing their useless kids as "assistants"

So, burning 1870L of petrol at 720g/L (1346KG of petrol) makes 4.9 tons of CO2??????
The greenies should have invested in a solar powered calculator, I'll mail them one via Australia, that should raise their blood pressure.

that is correct!! I also do not understand how this can be possible, one litre which as you correctly say weighs 720g (actually 737g at 60C) when burnt apparently produces 2.39tons of CO2, diesel which weighs about 900g (again temp dependant) per litre produces 2.62 tons due to a higher carbon content.
what i am trying to find out as this thread had sparked an interest in picking holes in CO2 BS is is a ton of CO2 really a ton? Gas is normally measured by volume not mass, and the volume is (normally) measured by flow which requires a flow orafice and a pressure difference across thjis orafice (called delta P)
I think we may find that 720grams of petrol which is a real mass does not produce 2390000grams of CO2 gas!!!

Things like this really get my back up, along with 'the governments saviour scrappage scheme' and words like 'Eco' and 'Green'....
Generally the problem is that, really dull, bullied, middle of the road, average and ugly people are the only ones who want to work in politics or for the government and usually these people tend to be tree-hugging hippies who hate cars and anything remotly fun that has an engine....so us normal oily-fingered hard-working folk dont really stand a chance do we?

Well, according to the New Scientist, a good way to reduce carbon emissions is to use Urine to fertilise plants, rather than a manufactured product. Simple really, drive into the countryside in your E30 and relieve yourself on a farmers field.

It's kilos, not tons.
Petrol is a hydrocarbon, therefore, two hydrogen atoms bond with one oxygen, to produce H20.
The carbon atoms bond with two oxygen atoms, to produce CO2.
Hydrogen has an atomic mass of 1, oxygen has an atomic mass of 16, and carbon is 12 (roughly).
So, one H2O molecule has an atomic mass of 18, and one CO2 molecule is 44 in atomic mass.

Here's someone who's paid attention in Chemistry. Ok, so I realise that C02 = 1 Carbon atom + 2 Oxygens, and petrol is made up of hydrogen and carbon.
Comparing just atomic masses, how much does 1 molecule of petrol increase in atomic mass by when burnt, and what proportion becomes H2O and CO2?

Petrol isn't made of one type of hydrocarbon. They vary between 5 to 12 carbon atoms in the chain, but one of the main constituents is heptane. Since it's an alkane, it is C7H16.
Its atomic mass is 100.
Now, the burnt products; the H20 (8 of them) has an atomic mass of 144.
The CO2 has an atomic mass of 308.
The grand total of the burnt products is 452.
That is an expansion of 452%.
Now, if we use 100 octane fuel, there is more isooctane (C8H18) present, then the expansion is 514%.

Ahha, there is the flaw in my calculation!!! and yes you are right reading back it is indeed kgs...god only knows where i got tons from
but in my defense the first calculation was right!! EDIT - no its wrong too

no E30 will average 8litre/100km, more like 8km/litre or 12.5 l/100km which means the 4.9 tons of CO2 comes only in 15,000km or 9350 miles!! So in response ot the OP 4.9 tons of CO2 is nothing!!!!
and further messing about has found a ton of alumium takes about 14500kWh which is more like 7-8 TONS!! of CO2
so there are yet more flaws in my arguments and logic!!
that'll teach me!

Don't panic, because if you think all this through on a rational basis;
The CO2 emissions create acid rain which will kill off the rainforests and cause global warming, but the rotting pulp of the resulting decaying tree matter will eventually make more oil, and the warmer climate will lessen our requirement to use the existing reserves of oil/gas/coal for heating.
Meanwhile, rising sea levels will leave less land thus cutting journey distances on land and further saving fuel.
So, nature automatically balances out any human activity.
Also, back on topic of the carbon offset debate, I discovered a bag full of carbon dynamo brushes at the back of my garage today, so it looks like I for one am well on track to meet my Coyote treaty targets for this year

I don't know sh1t about chemistry but surely a lot of the CO2 comes from the whole combustible mixture of air and petrol not just petrol? Also perhaps they just stay out of the argument but is there anyone about who likes cars but also has a rational attitude to global warming and its consequences rather than just denying it, complaining about taxes or making jokes about the weather?

Yes, burning anything can't be good. I cycle to work every day, my wife works 3/4 mile from home and often walks/cycles if she's not using the car for work, my house is well insulated, I use energy saving light bulbs. That keeps my conscience clean enough.
But at the weekend. . . If I see a hybrid

car I drive faster, safe in the knowledge the average polution output will be low. LOL

Spotted an article, in one of the Sunday papers, where in a certain Scandanavian
country, they are using the corpses of 6000 culled rabits as heating fuel.
A new slant on bunny boiler.
